ing 01 from a driver pulley 66.

After leaving the circular guide 46, the strip is finally drawn downaround the rewind roll 53 which is supported on a center 5! extendingfrom a large flat disk 52, which is frictionally driven by mechanism,the speed of which is regulated according to the diameter of the rewindroll. This fiat disk 52 is pivoted on a frame 53 which extends from themain frames of the machine and is supported on a shaft 54 centered inthe two main side frames. A bracket 55 is braced between the outer endof frame 53 and the side of base 2| to act as a support for the rewindmechanism.

The main driving connections are established by means of belts andpulleys and their general location can be noted on Fig. 1. There it isseen that the shaft of motor M carries a pulley 50 which acts as a drivefor a belt 6i which is wound around a larger pulley 52 connecteddirectly to the main drive gearing of the printing mechanism. Alsoconnected to pulley 62 is a small pulley 53 for operating a belt 64cooperating with a large pulley 65 mounted on the shaft 54 alreadymentioned as the rewind driving shaft.

This shaft carries a small pulley 66 for supporting a belt 61 which istwisted to cooperate with a small pulley 68 swung out on an arm 59 andmounted on a movable vertical center in connection with a frictiondriving wheel 295 for rotating the rewind disk 52.

Regarding the rewind operation, it is already explained with referenceto Fig. 1 that the rewind roll 50 is located on the shaft 5| extendingfrom a friction disk 52 which is driven by belt- Reference to Fig. 4shows the parts in a plan view and there the supporting bracket 53 fordisk 52 and shaft 5| is seen to be secured to a shaft 54, which runsthrough th main side frames 22'and 23 and on its two ends carries thepulleys 65 and 66. There it is also noted that the friction drivingwheel 295 is carried on a swinging arm or lever 69 also pivoted on shaft54.

On the end of rocking lever 69 there is pivoted at 28! a rocking frame288 which carries a U-shaped bar 289 for supporting the friction drivingwheel 295. Mounted as an L-shaped extension from rocking frame 288 is asupporting member 290 for carrying a freely turning follower roller 29!which rests' on the periphery of the rewind roll 50 and serves to followthe enlargement of the diameter of this roller and thereby swing theoperating point of the friction drive out toward the enlarged diameterof the friction disk 52, so the rewind action is constantly proportionalto the size of the rewind roll.

In Figs. 2 and 3 the rewind driving parts are shown in greater detailand in the sectional view (Fig. 3) it is seen that a number of parts areconfined between the extending ends of the U-shaped hanger 289. Near thetop of the hanger is the driving pulley 68 containing a ball bearing 292for permitting it to rotate freely on a vertical shaft 293 passingthrough openings in both ends of the arms on the hanger. Th pulley 68 isseen to be formed with a cylindrical extension 294 upon which isfastened the friction driving wheel 295 as a conical ring of rubber orother frictional material shaped to cooperate with the side wall of thefriction disk 52. Insid the lower end of cylinder 294 is another ballbearing 296 encircling the shaft 293 and insuring free rotation of theconnected part on this shaft.

Shaft 293 also carries a means for throwing off the friction drivingconnections so that the rewind may be disabled at any time. Thesethrow-off connections are pinned to opposite ends of shaft 293. At theupper end of the shaft is fastened an extending arm 29'! (Fig. 2)cooperating with a stop pin 298 which extends from the top of hanger 289for limiting the rocking movement of the lever. At the lower end ofshaft 293 (Fig. 3) is fastened another arm 309 carrying a roller 30!normally out of contact with the face of disk 52. However, when arm 29'!(Fig. 2) is rocked counterclockwise for the throwing-01f operation, arm380 is moved in the same direction and roller 30! presses against theside of the friction disk 52 and shaft 293 is shoved away from the diskso that the friction driving wheel 295 is moved out of cooperation withthe disk. When the parts are so situated, the pulley 68 and frictiondriving wheel 295 are allowed to operate without communicating anydriving action to the rewind roll.

A plan view of Fig. 2 shows the details of the connection between theswinging frame 288 and the holder 290 for the follower roller 29!. Theconnection involves a hinged construction 303 where the end of frame 288fits into a recess'cut in the side of the member 290. There is a certainamount of play in the joint allowing the roller to move back and forthin following the periphery of the rewind roll. To hold the partstogether the end of frame 288 is formed with a T-shaped recess in whichfits the head 304 of a bolt which is tightened on the outside of member290.

In order to uphold the swinging arm 69 and the rewind drive partsthereon (Fig. 4), a spring 305 is attached to a stud 306 extending fromframe 23, and at its opposite end is connected to a rod 301 which isfixed to a bracket 308 extending horizontally from the carrying arm 69.Reference to Fig. 1 shows that the link 30Tis shaped to encircle theoperating shaft 54. The spring not only tends to swing the rewind partsagainst the side of friction disk 52, but it also tends to hold the endof the lever 69 down so that roller 29! is maintained in contact withthe top of the rewind roll.

A compensating means is provided for swinging frame 288 so that itfollows more closely to a radial line of movement across the surface ofdisk 52 rather than in arcuate path of travel, which would prevail ifthe holder 288 were fixed to theend of arm 69. Seeing that the parts arepivoted at 287, it is possible to rock the frame 288 toward the right(Fig. 1) as it is elevated and thus flatten out the arcuate pathoftravel. For this purpose a link 3l0 is articulated at 311 on thebottom end of frame 288 and the opposite end of the link is pivoted at 3l 2 on the stationary supporting frame 53.

While there have been shown and described and pointed out thefundamental novel features of the invention as applied to a singlemodification, it will be understood that various omissions andsubstitutions and changes in the form and details of the deviceillustrated and in its operation may be made by those skilled in the artwithout departing from the spirit of the invention. It is the intentiontherefore to be limited only as indicated by the scope of the followingclaims.
